Copper has high conductivity compared with other metals. It is used for parts of electric equipment with the characteristic.
Copper has high thermal conductivity. This characteristic is utilized for the cooking tools such as pans.
Copper has antimicrobial activity with oligodynamic metal action. And it is verified that antimicrobial copper has effect on enteropathogenic Escherichia coli (i.e. Escherichia coli O157).
Copper is tough even if it is stretched and forged. Copper is workable and suitable for bending and drawing.
Copper has beautiful color and luster. Copper is used for building materials because of the fine surface.
